Answer:

50x⁴ - 20x² + 1 = 0

1. Quadratic form

50(x²)² - 20x² + 1 = 0

2. U is

x² = u

3. U- substitution

50u² - 20u + 1 = 0

4. Find the discriminant and identify roots

d = (-20)² - 4*1*50 = 200
u = (20 ± √200)/100
u = (2 ± √2)/10

Solve for x

x² = (2 ± √2)/10
x = ± √((2 ± √2)/10), four roots

What is the SUM of the angle measures in a nonagon (9 sides)?

GenaCL600 [577]

Answer:

All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1260 degrees (from above)... And there are nine angles... So, the measure of the angle of a regular nonagon is 140 degrees.
